YZ450F

YZ450F

Forward-thinking

With its rearward-slanted cylinder and innovative reverse 4-valve cylinder head featuring a highly efficient front-facing inlet, this hugely capable motorcycle has reaffirmed its status as one of the most competitive motocross bikes at every level. Its ability to win 'straight from the crate' - combined with Yamaha's high levels of reliability and durability - has made the YZ450F the clear choice amongst many local, national and international racers.

Yamaha's engineers have focused on honing and refining the YZ450F in order to maintain its winning advantage - whilst at the same time delivering even higher levels of performance, controllability, feel and usability. Yamaha's MX development team persisted in thinking forward to introduce a wide range of engine and chassis changes to bring the YZ450F to the next level, with 4 key objectives:

  • Achieving a smoother and easier engine character for enhanced controllability and usability without sacrificing power output
  • More effective bump absorption, as well as improved controllability, traction and front grip feeling 
  • Improved braking power and controllability 
  • Faster race starts using an electronic Launch Control System

About Us

Doyle& Shields was established in 1973 by motorcycle enthusiasts Neville Doyle and Max Shields. Neville Doyle is the legendary motorcycle tuner behind the late Gregg Hansford and the Kawasaki Race Team of the 1970s and 80s.

In the mid-80s the business was acquired by Trevor and Jan Williams and Kevin and Anne Doyle, bringing their sharp competing skills to the business. Trevor and Kevin had previously had a very successful motorcross career: Trevor won multiple Australian Motorcross titles with Kevin as his mechanic.
